Artikel
10/19/2012

Gets the Cursor object that generated the CursorInRange event.

Namespace: Microsoft.Ink
Assembly: Microsoft.Ink (in Microsoft.Ink.dll)

Syntax

'Declaration
Public ReadOnly Property Cursor As Cursor
'Usage
Dim instance As InkCollectorCursorInRangeEventArgs 
Dim value As Cursor 

value = instance.Cursor

public Cursor Cursor { get; }

public:
property Cursor^ Cursor {
    Cursor^ get ();
}

public function get Cursor () : Cursor

Property Value

Type: Microsoft.Ink.Cursor
The object that generated the CursorInRange event.

Remarks

The Microsoft.Ink.Cursor class is not to be confused with System.Windows.Forms.Cursor class. Microsoft.Ink.Cursor represents general information about a tablet pointing and selecting device, usually a pen, while System.Windows.Forms.Cursor represents the image used to paint the mouse pointer.

Examples

In this example, when the CursorInRange event fires, a check is made to see if this is the first time that the InkCollector object has come in contact with this particular Cursor object. If so, the DrawingAttributes property is assigned with a clone of the DefaultDrawingAttributes property. This ensures that subsequent access to the DrawingAttributes property does not throw a null reference exception.

Private Sub mInkObject_CursorInRange(ByVal sender As Object, ByVal e As InkCollectorCursorInRangeEventArgs)
    Const MOUSE_CURSOR_ID As Integer = 1
    If e.NewCursor Then 
        ' mInkObject can be InkCollector, InkOverlay, or InkPicture
        e.Cursor.DrawingAttributes = mInkObject.DefaultDrawingAttributes.Clone()
        ' if this cursor is the mouse, we'll set color to red 
        If (MOUSE_CURSOR_ID = e.Cursor.Id) Then
            e.Cursor.DrawingAttributes.Color = Color.Red
        End If 

    End If 
End Sub

private void mInkObject_CursorInRange(object sender, InkCollectorCursorInRangeEventArgs e)
{
    const int MOUSE_CURSOR_ID = 1;

    if (e.NewCursor)
    {
        // mInkObject can be InkCollector, InkOverlay, or InkPicture
        e.Cursor.DrawingAttributes = mInkObject.DefaultDrawingAttributes.Clone();
        // if this cursor is the mouse, we'll set color to red 
        if (MOUSE_CURSOR_ID == e.Cursor.Id)
        {
            e.Cursor.DrawingAttributes.Color = Color.Red;
        }
    }
}
